[0027] As shown in FIG. 3, the mobile terminal 300 may include a
transceiver 310 for transmitting and receiving signals; first and
second camera units 320 and 330 for capturing still images and
videos; first and second display units 340 and 350 for displaying
images; a storage unit 360 for storing data; and a controller 370
for controlling the first and second camera units 320 and 330 and
controlling at least one of the first and second display units 340
and 350 to display at least one image captured through at least one
of the first and second camera units 320 and 330, an image received
through the transceiver; or an image stored in the storage unit
360.
[0028] The controller 370 may provide control such that an image
captured by the first camera unit 320 is displayed on the first
display unit 340 and an image captured by the second camera unit
330 is displayed on the second display unit 350, or may provide
control such that the images captured by the first and second
camera units 320 and 330 are all displayed on one of the first and
second display units 340 or 350.
[0029] In another embodiment, the controller 370 may provide
control such that the image captured by the first camera unit 320
or the second camera unit 330 or the image received through the
transceiver 310 is simultaneously displayed on the first and second
display units 340 and 350. So, the same image may be displayed on
both display units 340 and 350, respectively, or one image can be
divided into two parts and each displayed on one of the two display
units 340 or 350.
[0030] In one embodiment, the controller 370 may provide control
such that the image captured by the first camera unit 320 or the
second camera unit 330 is displayed on the first display unit 340,
and the image received through the transceiver 310 is displayed on
the second display unit 350, for example. Preferably, the
controller 370 may provide control such that the image captured by
the first camera unit 320 or the second camera unit 330 or an image
stored in the storage unit 360 is transmitted to a designated
subscriber (user) through the transceiver 310.
[0031] In certain embodiments, the controller 370 may provide
control such that at least one image captured by the first camera
unit 320 or the second camera unit 330 is stored in the storage
unit 360 and an image received through the transceiver 310 is
displayed on one of the first and second display units 340 or 350,
and an image for performing a function of the mobile terminal is
displayed on the other display unit.
[0032] In a preferred embodiment, the controller 370 may provide
control such that two or more images among the images are captured
through the first camera unit 320. The images captured through the
second camera unit 330, the image stored in the storage unit 360
and the image received through the transceiver 310 can be displayed
together on at least one of the first and second display units 340
and 350.
[0033] When two or more images are displayed on at least one of the
first and second display units 340 and 350, one screen can be
divided into multiple parts corresponding to the number of images
to be displayed on one screen. For example, the screen can be
divided according to a PIP (Picture In Picture) method. The divided
screen can have a main screen and at least one sub-screen. Based on
an importance of a pre-set image or the user's settings, a
relatively more important image can be displayed on the main screen
and a relatively less important image can be displayed on the
sub-screen. Images on the main screen and the sub-screen can be
switched. Thus, an image on the main screen can be displayed on the
sub-screen, or an image on the sub-screen can be displayed on the
main screen.
[0034] The controller 370 may provide control such that two or more
images are captured through the first camera unit 320, or through
the second camera unit 330. The images captured and stored in the
storage unit 360 and the image received through the transceiver
310, for example, may be combined to be displayed, stored or
transmitted.
[0035] For example, in case of video communications (e.g., video
telephony, video conference calls, etc.) as shown in FIG. 4, the
controller 370 may provide control such that an image received from
the other party is displayed on the first display unit 340, and an
image of a user captured by the first camera unit 320 or the second
camera unit 330 is displayed on the second display unit 350. Also,
images received from three or more people can all be displayed on
the first display unit 340 by dividing the screen of the first
display unit 340 and the image of the user captured by the first
camera unit 320 or the second camera unit 330 can be displayed on
the second display unit 350, for example.
[0036] Referring to FIG. 5, the controller 370 may provide control
such that the image received from the a third party is displayed on
the first display unit 340 and the image captured by the first
camera unit 320 and the image captured by the second camera unit
330 are displayed together on the second display unit 350 by
dividing the screen, for example.
[0037] Referring to FIG. 6, the controller 370 may provide control
such that the image received from another party and images captured
through the first or second camera units 320 and 330 are displayed
together on the first display unit 340 by splitting the screen, and
another image inputted through the first or second camera units 320
and 330 is displayed on the second display unit 350.
[0038] Referring to FIG. 7, the image received from another party
or the image captured through the first camera unit 320 or the
second camera unit 330 may be displayed on the first display unit
340, while the image for performing a function of the mobile
terminal, such as creating a message, can be displayed on the
second display unit 350, for example.
[0039] In one embodiment, considering the overall design of the
mobile terminal or to maximize the size of the display units, a
hardware type keypad may be omitted and the second display unit
350, for example, can have a touch sensitive screen to receive user
touch inputs. Preferably, both of the first and second display
units 340 and 350 can be touch screens.
[0040] Referring to FIG. 8, the controller 370 may provide control
such that the image received or the image captured by the first
camera unit 320 or the second camera unit 330 can be divided to be
partly displayed on the first 340 and second 350 display units,
respectively.
[0041] In one embodiment, as shown in FIG. 9, the controller 370
may provide control such that one of the images may be displayed
divided on the two display units 340 and 350, for example. In
another embodiment, as shown in FIG. 10, at least one of the images
can be scaled up or down (i.e., magnified) through a zoom function
(e.g., lens hardware or software) and displayed on one of the first
and second display units 340 and 350. The other image may be
displayed on the other display unit or the same display unit,
depending by implementation.
[0042] The controller 370 may obtain the image captured via the
first camera unit 320, or the second camera unit 330, or the image
received from another party, and store such image as a still image
or video in the storage unit 360, or may capture two or more images
and combine them into a single image and store it. In one
embodiment, the controller 370 may provide control such that at
least two or more images are virtually combined through a preview
function, and then the combined image is captured and stored in the
storage unit 360.
[0043] For example, as shown in FIG. 11, images are captured by the
first and second camera units 320 and 330, respectively, and the
respective images from the first camera unit 320 and the second
camera unit 330 are obtained simultaneously or within a certain
time interval, and then, combined into one image and stored.
[0044] Referring to FIG. 12, the controller 370 may control the
mobile terminal 300 such that at least two or more of the images
are virtually combined through a preview function. The virtually
combined image can be edited and stored. The controller 370 can
transmit the stored image after having been captured,
captured/combined or combined/captured to another subscriber (e.g.,
a mobile terminal of a different subscriber) designated by the user
or a particular server through the transceiver 310. The particular
server can be a telecommunications provider server or can be a
general server of a service provider that provides a particular
Internet service.
[0045] As mentioned above, at least one of the first and second
display units 340 and 350 can be formed as a touch screen and
perform a function of receiving touch sensitive inputs from the
user. The mobile terminal 300 may include an input unit such as a
keypad, a touch pad or a microphone, and may include an input
terminal for receiving a signal by being connected with an external
input unit such as a keyboard. The mobile terminal 300 may include
an output unit such as a speaker, or may include an output terminal
for outputting an image signal or a voice signal by being connected
with an external display unit such as a television or a
monitor.
[0046] The mobile terminal 300 may include other functional units
having a supplementary function such as a storage medium insertion
unit for allowing using of an external storage medium by inserting
an external storage medium such as a memory card, a broadcast
reception module, an MP3 module, an internet banking module, a
local area wireless communication module, etc.
[0047] FIGS. 13 to 15 are flowcharts illustrating the exemplary
processes of the image capturing and displaying method of the
mobile terminal according to the present invention. With reference
to FIG. 13, the image capturing and displaying method in the mobile
terminal which has at least two display units and at least two
camera units, may comprise displaying at least one image on the
first display unit 340 (S1310); and displaying at least one image
on the second display unit 350 (S1320).
[0048] Referring to FIGS. 4 to 10, at least one of the images
captured by the first camera unit 320, or the second camera unit
330, or an image received from another party, or a previously
stored image can be displayed on the first display unit 340, or on
the second display unit 350. At least one of the first and second
display units 340 and 350 can display an image for performing a
function of the mobile terminal 300. In some embodiments, when two
or more images are displayed on at least one of the first and
second display units 340 and 350, the screen can be divided or
split up (e.g., a PIP method) in order to display multiple images
on each screen.
[0049] Referring to FIG. 14, the image capturing and displaying
method of the mobile terminal may further comprise capturing and
storing at least one of the images displayed on the first and
second display units (S1410). The two or more captured images can
be, for example, combined into one image and stored.
[0050] As shown in FIG. 15, the image capturing and displaying
method of the mobile terminal 300 may further comprise combining at
least two images displayed on the first and second display units
340, 350 and capturing and storing the images (S1510). In one
embodiment, a virtual combining is performed on the screen through
the preview function and then the virtually combined image is
captured.
[0051] Although not shown, the image capturing and displaying
method of the mobile terminal 300 may further transmit the stored
image to a different subscriber or the particular server. As so far
described, the mobile terminal and the image capturing and
displaying method using the same according to the present invention
have many advantages.
[0052] Preferably, at least one image can be captured and displayed
in various forms through the two or more cameras or two or more
display units. Two or more images can be displayed on one display
unit, while an image for performing a function of the mobile
terminal can be displayed on the other display unit, whereby the
user can freely perform different operations (i.e., can perform
multi-tasking) by using the mobile terminal 300 even while video
telephony or image capturing is being performed. Moreover, two or
more images can be combined to create a new image.
[0053] The foregoing embodiments and advantages are merely
exemplary and are not to be construed as limiting the present
invention. The present teaching can be readily applied to other
types of apparatuses. The description of the present invention is
intended to be illustrative, and not to limit the scope of the
claims. Many alternatives, modifications, and variations will be
apparent to those skilled in the art. In the claims,
means-plus-function clauses are intended to cover the structure
described herein as performing the recited function and not only
structural equivalents but also equivalent structures.
